UASB+ALR处理晚期填埋垃圾渗滤液

Treatment of Landfill Leachate by UASB-ALR Process

采用UASB-ALR的组合工艺处理高氨氮晚期垃圾渗滤液。结果表明,经过55 d的启动后,该工艺进入稳定运行期。当进水COD和NH4+-N浓度分别为6628 mg/L和1060 mg/L时,系统出水COD和氨氮分别达到712 mg/L和140 mg/L。由此说明,仅仅通过生物处理很难使渗滤液达标排放,需要进一步的深度处理。

Landfill leachate with high ammonia was treated by up-flow anaerobic sludge blanket reactor （UASB） - Airlift Loop Reactor（ALR）process. The results showed that the process reaches the stable operation period after 55 d time. When the influent COD and NH4^＋-N reached 6628 mg/L and 1060 mg/L respectively, the effiuent COD and ammonia reaches 712 rng/L and l40 mg/L. Therefore, it is difficult to make the leachate to reach the discharge standard merely by the biological treatment and need the depth of treatment.
